Two things stack on each other here. First, the housing era: a door built around 1986 is past any reasonable service life for its springs, rollers, and factory finish, even if the panels themselves still look fine. Second, the climate. This area sits in a cold-severe band, and a single-layer, non-insulated door from that period was never built to hold a thermal break - it just wasn't part of the spec sheet back then. That combination means garages here run cold in winter regardless of how tight the house envelope is, and the original hardware wasn't engineered for the expansion and contraction cycles that cold brings. Springs lose tension faster, track alignment drifts, and seals that were marginal new are long gone now. None of that is unique to one house - it's the baseline condition for most of the original stock still standing in this area.
